Glad to see I'm not the only one still using Tcl :)

"even adding new widgets that Qt and and GNOME had that Tk didn't (trees, tables, buttons that could show images and labels, for example). Tk has since made this a lot easier but at the time it was frustratingly time consuming."

Can you open these up? More generally, is there a real CPAN for Tcl/Tk (and is there interest)?
